摘要: We studied pack size of Wolves ( Canis lupus ) on Woodland Caribou Rangifer tarandus caribou winter ranges in westcentral Alberta. These are experiencing increasing pressure from resource extraction industries (forestry, energy sector) and concerns have been raised regarding increased Wolf predation conjunction with landscape change. Thirty-one Wolves, eight packs, were fitted radiocollars two the Rocky Mountain foothills, near Grande Cache, Alberta (2000-2001). There was a mean 8.2 Wolves/pack between 30 39 each RedRock/Prairie Creek Little Smoky ranges. The average this region does not appear to over that recorded historically, but range (5-18) number per varied considerably our study area. preyed predominately Moose Alces alces ), averaging one kill every three five days. some indication related prey size, smallest preying Deer Odocoileus spp.). It clear could be primary for due their low numbers, relative kills we observed.
